ST. MORITZ, switzerland — It was definitely an up-and-down weekend in terms of results, but it is good to be back in Europe.

I’m living in my Red Bull bus again, my home away from home, and my sister Laura is here to travel with me.

My bus is brand new this season. It has all my workout stuff. It has a full kitchen, I have my own bedroom and Laura has a bed. It has a sweet flat-screen TV, a big living room and walk-in closets.

It’s nice to be able to come back after races and feel like you’ve come home, where you can sit and relax. Laura helps me with lunch and dinner, and I’m in charge of breakfast. We have a good system.

Laura is 22, one of the triplets in my family. She’s studying in Florence, Italy, but is taking a year off to travel with me, get some experience and help me out.

In the races here, I failed to finish a super combined, won a super-G and finished 27th in a giant slalom. Given that I’m trying to get my strength back after my hospital stay last month, having three races in a weekend is tough. I don’t have as much energy as I normally do.

In the giant slalom, I felt like I skied pretty well on the first run (fifth place), but in the second run I was dead. I didn’t have any gas left in the tank. I tried to risk everything and get on the podium, but I made a mistake and just didn’t have the strength to recover from it. I was really bummed out, because I had a really fast split time on the top. I felt like I had a chance to be on the podium, but then my strength failed me. That’s just never been a problem for me.

It’s definitely a struggle, not just physically but mentally. I can’t rely on my strength the way I have in the past, because of my illness. I have to be patient, because I know it’s going to turn around. I just have to try my best to get in some extra workouts when I feel like I have the energy.

And the next couple of weeks will be tough. After a downhill Friday and a super-G on Saturday in Val d’Isere, we travel through France to Courchevel for a giant slalom on Sunday. Then we fly to Sweden for a giant slalom Wednesday and a slalom Thursday.

The schedule definitely isn’t working in my favor at this point, but I’m hoping I’ll be able to recover over the Christmas break.
